On the next page of the Guide to Control, you will find a description of the mission Polaris. You will learn, e.g. how to navigate the Ashtray Maze, solve the puzzle with the picture, and eliminate the Hiss from the satellite.
Making the way through the Ashtray Maze
Return to the Ashtray Maze with the tape player. From then on, its layout will look completely different. You can feel like a hero of a music video, running through the corridors of the maze, listening to the background songs of Ahti. Of course, to keep things engaging, there are many enemies that will prevent you from completing the stage.
The maze is quite straightforward and easy to navigate. Every time, you have only one exit from a given room, no matter what transformation the area undergoes. At some points, you will need to use levitation, or evading to quickly get to another place. After a while, you will finally reach the Firewall.
The way to the Hedron Chamber
Take the checkpoint in the Dimensional Research. Then run to the Hedron Chamber. After a while, you will reach the panel, draw an identical shape with a line, as can be seen on the sheet of paper. Thus, you unlock the passage to the aforementioned chamber.
Satelites and combat
Go to the big door and remove the screws from them. You are now in an area with a lot of enemies. Defeat them, then clean three satellites of The Hiss.
After all, the big object will fly up - use levitation to follow it and defeat the enemies in the next level, then clear more satellites. Fighting opponents can be quite tiresome, so be careful as in case of failures, you have to repeat the entire sequence from the beginning.
After a while, you will have to do the same thing - another level full of enemies and some satelites. As before, fight enemies and watch your health. In case of problems, you can retreat to an earlier platform to safely defeat enemies from here. Throw objects at them and use weapons to safely win the clash.
When you beat enemies, jump up all the way to Polaris. After a cut-scene... you'll see the end credits. However, do not turn off the game! In their course, something begins to happen, and you continue the story in the next, final mission - Take Control.
